[0002] Silicon carbide pipes are a type of pipe with excellent wear resistance, high temperature resistance, and corrosion resistance, and are widely used in various industrial fields.

[0003] Pipe connections are typically made using welding. During welding, specific welding materials are usually used, such as alumina oxide and silicon carbide particles. These materials have good oxidation resistance and mechanical strength, effectively resisting high temperatures and wear, ensuring the strength and durability of the weld. However, silicon carbide is a high-hardness, high-wear-resistant ceramic material with extremely high thermal and chemical stability. However, these excellent properties also make silicon carbide difficult to process and shape during welding, increasing the difficulty of welding and making subsequent repairs and replacements more inconvenient. Therefore, improvements are needed. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 5 As shown, this utility model provides a silicon carbide-lined pipe that is easy to connect and fix, including a pipe 1, a pipe 2 movably installed at the front end of the pipe 1, a cylinder 4 fixedly installed on the outside of the pipe 1, a slot 5 opened at the front end of the cylinder 4, and slots 6 opened on both sides of the bottom of the slot 5, a threaded groove 8 opened on the outside of the front end of the pipe 2, a cylinder 9 movably installed on the outside of the pipe 2, a thread 10 fixedly installed on the inside of the cylinder 9, the threaded groove 8 corresponding to the thread 10, the front end of the cylinder 9 movably connected to the inside of the slot 5, and a locking block 11 fixedly installed on the outside of the front end of the cylinder 9, the locking block 11 corresponding to the locking slot 6.

[0022] Pipe 1 and Pipe 2 are lined with silicon carbide. When connecting pipe 1 and pipe 2, first align the two ends of pipe 1 and pipe 2, then insert cylinder 9 into slot 5, so that the locking block 11 compresses the telescopic spring 7, causing the telescopic spring 7 to deform. Then rotate pipe 2, so that pipe 2 drives cylinder 9 to rotate, rotating the locking block 11 to the bottom of slot 6. At this time, after releasing, the telescopic spring 7 releases elastic potential energy to push the locking block 11 into the slot 6, thus completing the connection of the pipes.

[0023] By aligning the two ends of pipe 1 and pipe 2, and then inserting cylinder 9 into the slot 5, rotating pipe 2, and rotating the locking block 11 to the bottom of the slot 6, the telescopic spring 7 releases its elastic potential energy to push the locking block 11 into the slot 6. Compared with traditional silicon carbide lined pipes, this easy-to-connect and fix silicon carbide lined pipe can be installed by aligning the two ends of the pipe and then inserting and rotating it to the appropriate position, which is convenient for installation and disassembly.

[0024] Among them, a bottom ring block 12 is fixedly sleeved on the outer side of the second pipe 2, a connecting block 13 is evenly fixedly installed at the front end of the bottom ring block 12, an inclined elastic block 14 is fixedly installed on the outer side of the bottom ring block 12, a threaded groove 15 is opened on the inner side of the inclined elastic block 14, a threaded ring 16 is movably installed inside the threaded groove 15, and a retaining ring 17 is fixedly installed below the threaded ring 16.

[0025] The cylinder 9 is fixed to the front end of the pipe 2 by rotation. Then, the knob 18 is rotated, which drives the threaded ring 16 to rotate. The threaded ring 16 rotates and moves downward inside the threaded groove 15, which drives the retaining ring 17 to move downward and squeeze the connecting block 13. This causes the connecting block 13 to deform and shrink inward, thereby clamping and fixing the cylinder 9 to prevent the cylinder 9 from loosening and affecting the sealing performance.

[0026] By rotating and fixing the cylinder 9 to the front end of the pipe 2, rotating the knob 18 causes the retaining ring 17 to move downward and squeeze the connecting block 13, thereby clamping and fixing the cylinder 9 to prevent it from loosening and affecting the sealing performance. Compared with traditional silicon carbide lined pipes, this easy-to-connect and fix silicon carbide lined pipe clamps and fixes the cylinder 9 to prevent it from loosening and affecting the sealing performance.

[0027] A knob 18 is fixedly installed on the front side of the threaded ring 16, and the knob 18 is located on the front side of the inclined elastic block 14.

[0028] By rotating the knob 18, the knob 18 drives the threaded ring 16 to rotate, and the threaded ring 16 drives the retaining ring 17 to move downward to squeeze the connecting block 13.

[0029] The bottom of the slot 5 is elastically fitted with a telescopic spring 7, which is located inside the card block 11.

[0030] Insert the cylinder 9 into the slot 5, so that the locking block 11 compresses the telescopic spring 7, causing the telescopic spring 7 to deform. Then rotate the pipe 2, so that the pipe 2 drives the cylinder 9 to rotate, rotating the locking block 11 to the bottom of the slot 6. At this time, after releasing the hand, the telescopic spring 7 releases its elastic potential energy to push the locking block 11 into the slot 6.

[0031] Among them, annular grooves 3 are opened on the inner sides of both ends of pipe 1 and pipe 2, and the cross-section of the annular grooves 3 is triangular.

[0032] By opening annular grooves 3 at both ends of pipe 1 and pipe 2, the transport of materials within the pipes is facilitated, and the fluidity of the materials is improved.

[0033] The retaining ring 17 has a triangular cross-section and corresponds to the connecting block 13.

[0034] The downward movement of the retaining ring 17 presses against the inclined surface of the connecting block 13, causing the connecting block 13 to move inward under the pressure and fix the cylinder 9.

[0035] Working principle and usage process of this utility model:

[0036] Pipe 1 and Pipe 2 are lined with silicon carbide. When connecting pipe 1 and pipe 2, first align the two ends of pipe 1 and pipe 2, then insert cylinder 9 into slot 5, so that the locking block 11 compresses the telescopic spring 7, causing the telescopic spring 7 to deform. Then rotate pipe 2, so that pipe 2 drives cylinder 9 to rotate, rotating the locking block 11 to the bottom of slot 6. At this time, after releasing, the telescopic spring 7 releases elastic potential energy to push the locking block 11 into the slot 6, thus completing the connection of the pipes.

[0037] The cylinder 9 is fixed to the front end of the pipe 2 by rotation. Then, the knob 18 is rotated, which drives the threaded ring 16 to rotate. The threaded ring 16 rotates and moves downward inside the threaded groove 15, which drives the retaining ring 17 to move downward and squeeze the connecting block 13. This causes the connecting block 13 to deform and shrink inward, thereby clamping and fixing the cylinder 9 to prevent the cylinder 9 from loosening and affecting the sealing performance.
